Hey man, nice build, I have been working on a similar build also but with the 1.8l mazda bpt & not the gtr engine swapped into a mazda protege 5, will post some pics & progress info later as I still have to get it tuned, hoping to achieve 275 - 300 hp at the wheels.
Cheers, nice to see the old school engine beating up on my new school buddies, lol!
